Application August 2, 1950, Serial No. 177,168

This invention relates to an improved hook for use in drawing the warpthread through the reeds employed in weaving looms.

The primary object of this invention is to provide a hook which advancesgradually and automatically along the successive s lits in the reedduring the operation of drawing the several warp threads therethrough.

Another important object of this invention is to provide a reed knife ofthe character described which is relatively simple in design andconstruction, inexpensive to manufacture, and very easy to manipulate insuch a manner that an up and down movement of the knife will cause it toad- Vance automatically in step-Wise fashion along the reed as the warpthreads are being drawn through the successive splits.

Yet another object of this invention is to provide a warp drawing hookcomprising a blade formed with a notch intermediate its ends for thereception of the thread, a handle, pair of resilient supports secured insaid handle and receiving the lower end of said blade, and meansyieldingly securing said blade to said supports whereby the hook isgradually and automatically advanced along the successive splits in thereeds in response to an up and down movement of the hook.

These, together with various ancillary objects and features of theinvention which will later become apparent as the following descriptionproceeds, are attained by the device, a preferred embodiment of whichhas been illustrated by way of example only in the accompanyingdrawings, wherein:

Figure 1 is a perspective view of the device;

Figure 2 is an end elevational view of the device;

Figure 3 is a sectional view taken substantially on the plane of sectionline 3--3 of Figure 2, some parts being shown in elevation; and,

Figure 4 is a fragmentary side elevational view of the device shownengaged in the splits between the reed, the latter being shown invertical section.

Specific reference is now made to the drawings. In the several views inthe accompanying drawings and in the following specification referencecharacters indicate corresponding elements throughout.

Indicated generally at II) are the conventional v reeds employed inweaving looms separated from each other to form the split H2. Thepresent device is indicated generally at [4 and includes a relativelyflat elongated blade l6 having a hook H3 at its upper end serving as asto to limit the -1 Claim. (01. 28-45) downward movement of the device,the blade be-' ing received slidably in the split [2 between the reeds l0 and including oppositely extending, openended notches 20 for hookingand receiving the warp threads 22.

The device further includes a handle 24 having a collar 26 at its upperend. Secured by any appropriate means in the upper end of the handle 24are the outwardly bowed or angulated portions 28 of a pair of verticallyextending supporting plates 30, the upper free ends of the supportingplates including beveled ends 32 which are inclined in the samedirection. Both plates 30 are provided with vertically spaced,preferably dia-' mend-shaped apertures 34 and the blade It at its bottomend extends between the plates 30.

The plates 30 are resilient and may be spread apart but are so tensionedas to be normally urged towards each other and the blade I6 isyieldingly retained between the spaced plates 30 in the followingmanner. Adjacent its bottom end, the blade I5 is provided withoppositely extending, vertically spaced, laterally bowed or angulatedportions 36 and 38 which are normally engaged in the diamond shapedapertures 3'4 as shown clearly in Figure 3.

In use, the blade [6 is extended between the reed Ill through the splitsI2 and made to engage the warp thread 22 in the manner clearly shown inFigure 1. The blade is then moved downwardly by means of the handle 24whereby the thread 22 is made to extend between a pair of adjacentreeds. Subsequent upward movement of the device will cause one of theinclined edges 32 to engage one of the adjacent reeds and ride in thesplit therebetween, while the inclined end 32 of the other plate 30 willengage the other reed and ride in the next adjacent split. This otherreed will in effect be moved into the space between the bowed portions28 of the plate beneath the bottom free edge of the plate 16 and will be"pulled over so that, in effect, the blade It will be pulled into thenext adjacent split I2, as will be readily understood by those skilledin the art. Thus, by an up and down movement of the device, the bladewill be moved stepwise from split to split across the reed for theproper drawing of the warp thread through the reed.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description i accordingly deemed unnecessary.

It is to be understood, however, that even 3 though there is hereinshown and described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claim.Having described the invention, what is claimed as new is:

A warp drawing hook comprising a blade formed with a notch intermediateits ends for the reception of the thread, a handle, a pair of resilientupports secured in said handle and receiving the lower end of saidblade, means yieldingly securing said blade to said supports whereby thehook is gradually and automatically advanced along the successive splitsin the reeds in response to an up and down movement of the hook, saidsupports including plates having upper edges inclined in the samedirection and spaced from the blade, said means includingverticallydisaligned apertures in said support plates and 20 verticallyspaced, oppositely extending laterally bowed portions struck from saidblade in opposite directions and engaged in said apertures, said platesbeing yieldably tensioned and urged toward said blade, and a stop on theupper end of said blade limiting downward movement thereof.
